Robin and Richard, I started a dialog with Stuart Lewis a week or so ago about getting the Packager system improved upon. I also had a dialog with Richard about some of the BagIt packaging work he was working on. I've started to outline some requirements for furutre enhancements to the Packager system here:
https://wiki.duraspace.org/display/DSPACE/Refactor+Packagers+to+support+Chain+of+Command One of my intents here was to see that the METS crosswalk wasn't calling the METS Packager, but that it was the other way around, that the Packager processed a crosswalk to get the METS, the problem with the current approach is that it is conflating parsing the mets manifest with processing the zip file contents, we would like to see the processing of zip file contents be a separate stage from validating the manifest and assigning metadata, such we would gain the ability to extend a "ZIP Packager" to attain different packaging formats like Bagit and IMSCP, rather than having to implement the zip processing in those from scratch. My thought is that this would liberate us to have implementations for different METS profiles, SWORD, DSpace, even "type based" profiles like... https://pacer.ischool.utexas.edu/handle/2081/2066 Which IMO, was the original intent of METS, not Repository or Protocol centric packages, but Content Type Packages.
